This has led to continuous upgrades and improvements in the technology of air bubble film machines and bubble film making machines.
This article will provide a systematic analysis of mainstream bubble film machines in 2026 from multiple dimensions, including equipment structure, working principle, technological innovation, and brand selection.
Key Components of an Air Bubble Film Machine
A complete bubble film machine typically consists of an extrusion system, a forming system, a cooling system, a traction system, and a winding system. These components collectively determine the final quality and production efficiency of the bubble film.
Extrusion System
This is the core of the bubble film making machine, responsible for heating and melting the plastic raw material (such as LDPE) and extruding it uniformly. High-quality equipment is usually equipped with a high-efficiency screw design to ensure uniform plasticization and stable output.
Forming System
This module uses a die and vacuum adsorption structure to process the molten film into a film material with a uniform bubble structure. It is one of the key technological aspects of an air bubble film machine.
T-Die System
The die is made of high-quality die steel with a scientifically designed internal flow channel, effectively solving the problems of melt fracture and uneven thickness. For high-end bubble film machines, multi-layer co-extrusion dies can achieve precise lamination of 2, 3, or even 7 layers of film.
Automatic Winding System
The mainstream configuration in 2026 is a fully automatic flip-winding machine. It supports automatic cutting and automatic roll changing, and is equipped with a constant tension control system, which significantly reduces the frequency of manual intervention.

How Does a Bubble Film Making Machine Work
Understanding the operating logic of a bubble film making machine is crucial for optimizing production processes and improving product quality.
Feeding and Plasticizing: Raw materials enter the extruder barrel via an automatic feeder. In the heating zone of the bubble film machine, granular plastic is uniformly melted by an electromagnetic heating system.
Die Extrusion: The molten plastic is extruded through a T-die to form a uniform film curtain. At this stage, the film temperature is strictly controlled within the optimal lamination window.
Vacuum Forming: This is the most remarkable step in the air bubble film machine. The film is bonded to a perforated forming roller, and the plastic is drawn into the holes by the suction force of an internal vacuum pump to form bubbles.
Lamination and Cooling: If producing a 3-layer or multi-layer film, another planar film layer is immediately laminated with the bubble layer. Subsequently, the laminated film undergoes rapid shaping via cooling rollers to enhance the bubble-locking performance.
Slitting and Winding: The finished bubble film is slitting in an online slitting device to adjust its width as needed, and finally, the machine's power winding unit winds it into a neat finished product.
Mainstream Classification of the Air Bubble Film Machine
Based on structural design and functional differences, air bubble film machines on the market are mainly divided into double-layer, multi-layer, and co-extrusion equipment.
2-Layer and 3-Layer Basic Bubble Film Machines
As the cornerstone of packaging production lines, these two air bubble film machines, with their exceptional flexibility, have become the preferred choice for small and medium-sized enterprises and e-commerce packaging suppliers.
2-Layer Air Bubble Film Making Machine
This equipment is specifically designed to produce double-layer bubble film consisting of a bubble layer and a PE base film layer. Its core advantage lies in the independent control over raw materials, formulation, and color for each layer. This means that manufacturers can use transparent raw materials to produce the bubbles on one side and recycled materials with branded colors to produce the base film on the other, thereby reducing costs while maintaining the appearance.
3-Layer Air Bubble Film Making Machine
This is a highly versatile bubble film machine. It can not only produce standard 2-layer film but also create a 3-layer structure of "PE flat film + bubble layer + PE flat film." This symmetrical structure encloses the bubbles in the middle, providing stronger pressure resistance and better flatness. Similarly, each of the machine's three layers supports independent formulation control, meeting customers' high-end needs for product customization.
High-end 5-layer and 7-layer Bubble Film Machines
With the development of cold chain logistics and the building materials industry, simple plastic bubbles can no longer meet the demands for thermal insulation and superior toughness.
5-Layer Air Bubble Film Making Lamination Machine
This high-performance air bubble film machine enables online lamination. In addition to producing conventional 2-layer and 3-layer films, it can also laminate PE coating materials together using hot-pressing technology to form a reinforced structure with a total of 5 layers.
7-Layer Air Bubble Film Making Lamination Machine
This bubble film machine further increases the number of lamination layers, up to 7. It not only possesses all the functions of a 5-layer machine but also achieves industry-leading levels in the fusion and stability of multi-layer materials. This equipment is ideal for producing heavy-duty thermal insulation materials and industrial-grade protective pads, demonstrating the high adaptability of bubble film making machines in complex working conditions.

This equipment employs a unique "three-in-one" co-extrusion structure, particularly suitable for HDPE or PP materials. Its bubble layer and bottom film layer are each composed of three fused layers. This design produces films with higher tear strength and stiffness, making it the ideal equipment for producing aluminum foil express envelopes.
Nylon Co-extrusion Air Bubble Film Machine
This bubble film making machine uses a "five-in-one" co-extrusion structure. Due to the introduction of a nylon layer, this bubble film has extremely strong air-locking properties, reducing the air loss rate within the bubbles to an extremely low level. It is the preferred choice for precision electronics, high-end cosmetics, and products requiring long-distance, long-duration international transport.
